Specifically, can someone recommend resources that continue from the end of this YouTube video: https://www.youtube.com/watch?v=uKqC5uHjE4g&t=2s&ab_channel=zetamath?
Additionally, are there any alternative approaches, such as the Riemann-Siegel integral formula (https://mathworld.wolfram.com/Riemann-SiegelIntegralFormula.html), that refine the use of complex contour integration for finding zeros? Explanations for these alternatives would be greatly appreciated. Thanks.
Till now I found:
